    Built-in multi-satellite multi-frequency measurement antenna specification
    创始人2025-01-13

    The TDXL-BA700 is a multi-satellite, multi-frequency GNSS high-precision measurement antenna that supports the reception of satellite navigation signals from BDS, GPS, GLONASS, and GALILEO systems. It meets the current demands for multi-system compatibility and high-precision measurement and can be widely applied in geodetic surveying, marine surveying, precision agriculture, deformation monitoring and other high-precision navigation and positioning scenarios.

    1、Using multi-feed miniaturized technique, the antenna enables the right circular polarization and phase center performance, as well as minimizes the impact of measuring error;

    2、The antenna unit offers high gain and minimal gain roll-off, providing excellent reception of low elevation satellite signals and ensuring normal reception in severely obscured locations.

    3、The reactance network suppression technology is adopted to effectively reduce the interference of multipath effects on signal reception, ensuring measurement accuracy.
